FS90/FS90 Plus System

This system was introduced in the mid 1980's. This was a premier Fire Alarm System at the time. It was introduced as a complement to the Excel Plus HVAC system. The system can execute fire codes fo the US, Canada, UK, Germany and Australia . The system is basically a series of card cages with each card having a group of function cards installed. The different fucnctiopn cards are for different fire alarm functions. You have to know extensively about fire systems in order to configure the panel. The fire database for each panel is created off-line using special programmin/engineering tools and is not straight forward. But once programmed and engineered the sytem is extremely stable and reliable. The system uses nominal 28 VDC and has its own transformers.

The FS90/FS90 can also work as a standalone system and has the necessary user interface built right into the local opanel as required by the NFPA. Each FS90 panel can have 4 mother boards with a maximum of 32 function cards. Each panel can control practically hundreds of devices. The panels can be networked together on a proprietary bus caled the F & S Bus. There can be 29 panels per bus.

 

 

The FS90/FS90 Problems and the Resolution


The system was designed with database reliability in mind. For this reason the database is created off-line and then installed in the relevant distributed processors via special storage computer chips. That way power losses and other lapses have no effect on the system operation.

This is indeed a nice feature. Howerver, it does have some consequences. 

1. The off-line created database must be available to make any changes that may be necessary after the original system installation. Or, if the chips are corrupted or damaged that contain the databse for each panel, the original database will be rquired. But this database is typicaly not supplied to the customer via the liability arguments built into the original contract.

2. It is impossible to diagnose the system problems without access to this databse. Worse yet, the database is not in any text format and cannot be edited via some word processor. Instesd it must be looked at via the special programming tools created for controlling this databsae.

3.     The net result is that most service providers will not be able to service this system. They can only replace the hardware and even that basically will be just replacing each piece with the exact same hardware and this hardware is now available in very limited quantities. In most cases, the service provider will be calling Honeywell and they will be back on site as sub-contrators and Honeywell still will not release the database to the service provider and instead will simply "fix" the problem that they can decipher. But even Honeywell may not have all the resoures to work on this system. So they will be recommending costly upgrades! The customer will be paying large sums to the service providers and will be getting minimal functionality back since the sytem cannot be worked on without the availability of the system database. This is a huge loss and can be very frustrating for the customer.

4. The service providers will mainly concentrate on power cycling the system or just checking the system battery voltages and maintaing the system hardware and "testing" the smoke detectors periodically.

But what can CITS DO?

CITS Advisory:

You can find some parts on Ebay. But remenber that those are basiclly ex-Honeywell technicians that took some systems down and the hardware they have, they have no way of testing it. It can actually cause more problems than it will solve.
